🗞️ Driving the news: The United Kingdom and the European Union have reached an agreement in principle to link their emissions trading systems (ETS), according to four people briefed on the negotiations
• The deal, expected to be unveiled at a UK–EU summit in November, would reconnect carbon markets after Brexit and is intended to help businesses avoid additional costs under the EU’s Carbon Border Adjustment Mechanism (CBAM)

🔭 The context: Linking the systems was one of three areas targeted for agreement at last year’s UK–EU summit
• The other two, an agreement to ease agricultural and food trade checks and a youth mobility scheme, remain under negotiation, and the sides have said the three agreements will be treated as a package
• Both the UK and EU are preparing their own carbon border mechanisms for 2027
• Linking their ETS markets could also increase liquidity and improve carbon-market efficiency, although the UK’s carbon price is currently lower than the EU’s

🌍 Why it matters for the planet: Carbon pricing makes polluting activities more expensive, creating incentives for businesses to reduce greenhouse gas emissions
• Linking the markets could strengthen coordination between the UK and EU, but its climate impact will depend on the rules adopted and whether carbon prices encourage meaningful emissions cuts

⏭️ What’s next: The agreement still awaits official announcement and implementation details
• Negotiators would need to also resolve outstanding issues in the wider package, including tuition fees for EU students at British universities and potential caps on youth mobility visas
• Critics warn that aligning the systems could raise short-term costs for some UK businesses

💬 One quote: The two sides are now just “tying a ribbon” on the agreement, according to an EU diplomat quoted by POLITICO

📈 One stat: 1 January 2027 — the scheduled start date of the UK’s Carbon Border Adjustment Mechanism, which could impose costs on imports based on their embedded emissions.
